    摘要： Methods, systems, and devices for utilizing flexible bandwidth carriers for small cells are provided. Bandwidth scaling factor(s) for a small cell may be determined. A flexible bandwidth carrier may be generated for the small cell utilizing the bandwidth scaling factor. Some embodiments provide assistance with active hand-in due to more available PN offsets in the flexible bandwidth domain. Some embodiments enhance small cell discovery with high bandwidth scaling factor beacon-like small cells with little more power than that corresponding to the same power spectral density for normal bandwidth small cell. Some embodiments reduce the interference caused by small cell to macrocell users using an adaptive bandwidth scaling factor for small cells based on number of users supported and their traffic demand, to control the extent of overlap the macrocell has with small cell and the interference to macrocell mobiles. Some embodiments utilize self-configuration for small cells utilizing flexible bandwidth channels.

    摘要： Management of user equipment (UE) proximity indications to femto access points is provided using out-of-band (OOB) signals. To obtain OOB identification information on the femto access point, the UE determines the OOB identification information when in proximity to cells neighboring the femto access point. This OOB information is stored in a search information database (SID) of the UE and related to in-band information on the femto access point. To later determine proximity to the femto access point, in response to detecting its presence within a fingerprint area around the femto access point, a search for the femto access point is triggered using the OOB radio resources and OOB identification information associated with the femto access point in the SID. When the UE detects the femto access point using the OOB radio resources, the UE transmits a proximity indication to its serving base station over the in-band radio link.
